Full Stack Engineer
About Gains.com:
Gains.com is a fast-growing U.S.-based gaming and entertainment platform built
with a premium product mindset. We care deeply about trust, speed, and user
experience, and we move quickly as a small, highly aligned team.
This role sits on a small engineering team shipping the product end-to-end:
web, mobile, backend, and the operational tooling that runs the business
behind the scenes. You'll work directly with the CEO, CTO, design lead, and
the rest of engineering.
The Role:
We're hiring a Full Stack Engineer who can take a problem from ambiguous
request to shipped, tested, and monitored in production. You'll own features
across the stack and have meaningful input on architecture, prioritization,
and tradeoffs.
What you’ll be doing:
* Build features end-to-end across the Angular web app, Flutter mobile app, and Node.js backend
* Design schemas, write queries, and reason about transactional correctness in a system where money is the source of truth
* Ship to production multiple times a week behind CI/CD with strong test coverage and clear rollback paths
* Review teammates' code with care; expect the same in return
* Partner with design and product to scope down before scoping up
* Improve the developer experience around the monorepo, test harness, deploy pipeline, and observability
* Use AI coding tools as part of your daily workflow. We're an AI-native team and expect leverage, not just typing speed
Requirements:
* 5+ years of professional full-stack experience
* An advocate for strong engineering principles including CI/CD automation, high test coverage, thorough code reviews, and scalable system design.
* Experience designing and querying relational databases at scale; comfortable reasoning about schema design, indexes, transactions, and query performance
* Working knowledge of at least one major cloud provider such as GCP (preferred), AWS, or Azure — provisioning services, IAM, secrets, logging, and tracing
* Strong testing discipline — unit, integration, and ideally end-to-end tests
* Strong product sense — willing to weigh trade-offs, push back on scope, and ship the smallest thing that actually solves the problem
Bonus Points:
* Solid Angular web experience; comfortable with standalone components, signals, RxJS, and reactive forms
* Flutter / Dart for mobile native
* Node.js backend experience, including REST APIs, middleware, sessions, and rate limiting
* Firebase (Auth, Cloud Functions)
* Git + PR-based collaboration, code review etiquette, clear commit hygiene
* Comfortable in a monorepo workflow (i.e. Nx) and shipping changes that span multiple packages
* Strong TypeScript / ESM fluency
* Comfortable working with AI coding tools (Claude Code, Cursor, Copilot) as a daily-driver multiplier
Perks:
* Comprehensive medical, dental and vision insurance with employer contribution for yourself and your dependents
* Stock options
* Unlimited vacation and sick days
* Brand new Macbook Pro
* Remote-first work environment with flexible working hours
* Competitive salary
* High ownership, low bureaucracy
* Direct access to leadership
